The invention relates to fireproof vaults which may be, made ofconcreteor other fire resisting materials, and which include fireproofdoorsand jamb frames and vestibules therefor.

It has been the usual practice in constructing andinstalling the doorsfor such vaults, tofprovide, for the doors, jamb frames and vestibuleshaving straight sides. Whensuch door frames are installed,rthe openingthere'- for, out in. thewall of thevault', has suficient clearance toadmit the straight sided vestibule and jambs, thereby forming straightand direct passagesways about the j amb frame and vestibule between thesame and the opening in the vault wall.

When such door framesv are properly installed, these straight and directpassageways are filled with grout or like material, but it has beenfound in practice that workmen omit to fill these passage-ways withgrout, whereby even though the front of the jamb frame may be providedwith an architrave covering the front end of these passageways, heat asfrom fire and the like infront of thevault doors soon warps thearchitrave, and the passage-ways then become straight and direct flue 'swhich carry the heat from the, outside of the vault to the interiorthereof.

Accordingly, the objects of the present iminmates at its rear end in aninwardly directedfiange 16, and the inner rearwardly directed wall 15terminates at itsinner end in provements are to, provide a vaultconstruction which will overcome the difficulties incident to the usualpractice as aforesaid, by providing means effectually stopping thedirect passage of heat between the door jamb frame and vestibule and thevault wall open- '%hese and ancillary objects are attained by aconstruction and arrangement which may be stated in general terms asincluding in a vault and the like, a door jamb frame and a vestibuleconnected with the frame, and the frame including fireproof materialpref erably completely filling a metallic casing extending outwardly,from the vestibule walls, the outwardly extending fire-proof frame beingarranged to. be inserted in a rabbeted seat formed at the front side ofthe door opening in the vault wall, whereby even though grouting isomitted, a direct passage-way or flue for heat from the front of thevault to the interior is blocked.

A preferred embodiment of the invention is illustrated in theaccompanying drawings forming part hereof, in which I Figure 1 is avertical sectional view of the improved vault construction, as on line1-1, Fig. 2.

. Fig. 2, a horizontal cross section of the improved construction as online 22, Fig. 1.

Similar numerals of reference indicate corresponding parts throughoutthe drawings.

The improved vault construction indicated generally at 10, includes doorjainb frame side members 11 and 11 and top and bottom members 11 and 11.

Each of the frame members preferably includes a metallic casing 12having a front wall 13 with an outwardly opening groove 13 and anoutwardly projecting tongue 18 formed therein, for receiving an inwardlyprojecting tongue and an inwardly facing groove in the door, hereinafterto be described.

Each of the jamb frame casings further includes an outer rearwardlyextending wall 14 and an inner rearwardly extending wall 15 preferablyintegral with and extending from the edges of the front wall 13.

The outer rearwardly extending wall tererably completely filled with afireproofing J compound and the door frame thus includes fireproofmaterial completely engirdling the sides, top and bottom of the door,

and this fireproof door frame, as will herea inafter be set forth indetail, is located in a rabbeted seat preferably formed in the vaultwall at the front end of the door opening therein. Y 7

The inner rearwardly extending walls 15 of theamb frame form the frontend of the 19'. extending through suitable apertures in;

doorvestibule, and for providing vestibules of any desired length,vestibule side plates 21 and 21", and top and bottom plates 21 and 21,having outwardly extending flanges 22 at their front edges are securedto the j amb framemembers by means of the screws 19 pass through theapertures 25 and 26 and.

are screwed into the apertures 24 in the clamping plate 23. i 1

The vestibule plates 21 21 21and 21 may be of any desired depthfrom-front to rear for accommodating vault walls of any desiredthickness and are preferably providedat their rear edges with screwplates .27 spot welded thereto and threaded apertures. are provided inthe vestibule plates and screw plates, for receiving screws 28 whichpass through countersunk apertures 29 in a forwardly extending reararchitrave flange 30of the rear architrave plates 31.

Upon the jamb frame thus formed, a vault door 32 of any desired type,and which may be o'fthe type set forth in United States Letters Patent.No. 1,712,000, issued May 7, 1929, to Bruno T. Gialdini for vault doors,

' may be hung in a usual manner as by means 7 I of hinges 33.

The combined jamb frame and vestibule constructed as aforesaid thusincludes the casing 12 filled with fireproofing-compound 20, and thecasing\12 extends laterally outwardly from the vestibule members 21,-.21

21, and 21 and the outer faces F of the outer members 1 10f the frame,are laterallyv F off-set from theouter faces F of the members 21, 21*,21, and 21 of thevestibule; and the outerflfaces-of the casing member 18withthe outer faces F of the vestibule mem bers comprise an externalrabbeted seat in the combined jamb frame and vestibule.

For applying the aforesaid combined jamb frame and vestibule to a vaultin order to at tain the fire resisting advantages set forth, a

door opening 34 ismade in awall 35 of the vault, and the door opening isprovidedwith 1 laterally off-set faces 36 and 37 connected by a?laterally extending face. 38 intermediate.

the front and rear of the wall; and the faces 37 and 38 comprise arabbeted seat at the front end of the door opening for receiving thefireproof door frame; and "the vestibule members extend rearwardlyparallel withthe door opening faces36, there being suflic1ent clearancebetween the faces of the door opening and the faces of the jamb frameand vestibule to admit the jamb frame and vertibule into the dooropening and seat the frame in its rabbetedseat; and the outer face ofthe back walls 18 of the jamb frame casing preferably abuts against thelaterally extending faces 38 of the door opening.

Accordingly the frame extending laterally outwardly from the vestibulelaps over that portion-of the wall .extendinginwardly from the faces 37and the wall'ispreferably con"- structed of fire resisting material. Theaforesaid inwardly extending portions of the vaultwallfit in therabbeted seat of the combined frame and vestibule.

In other words the combined door frame and vestibule, and thedooropening are each provided with interfitting rabbeted seats, wherebythere is no direct passage-way from the outside of the vault totheinterior thereof between the door opening and the combined jamb frameandvestibule; i n

The usual type of vault construction in cludes a door opening havingstraight inner faces from front to rear and a door jamb frame andvestibule. having straight outer faces from frontto rear, there. beingthus formed straight and direct passage-ways about the jamb frame and.vestibule which lead directly from the outside of the vault to the.interior thereof in the event that the outer architrave is warped by theaction of heat and the like. '1 v I If the .usual vault. door isproperly installed, the, passage-waysare filled with grout or likematerial, but in. practice workmen often omit to fill the passage-wayswith grout, sothat the passage-Waysare straight and, direct flues whichcarrydheat from the outside .ofthe Vault to the interior thereof.

' It is obvious that the laterallyolfssetvfaces of the door opening andcombined door frame and vestibule of the improved construction hereinset forth.elimina'tethis direct flue material, the offset. closedclearance spaces 4-1 and 42 between the ofiset facesof the opening andframe.

I claim:

wall, and .a jamb frame and vestibule, the wall having a door openingformed therein and faces of the opening being laterally offset from eachother, and the .frame including fire resisting material and faces of theframe and vestibule being offset from each other and fitting with theoffset faces of the door opening. 1 I

Vault construction includinga vault Wall, and a jamb frame, the .Wall having a door opening formedtherein and having a rabbeted door frame seat formed therein at one endof the opening, and the jamb frame including fire resisting materialfitting in the seat.

In testimony that I claim the above, I have hereunto subscribed my name.
